This morning I read a comic book titled 'How to be a Man'. A 17 years old girl has a love interest who is 7 years younger than her. Eventually they dated each other.

The author said: "If I write a story with common theme, it will be too easy for the readers to guess where the story goes." He also said, "... I don't want you to become such person that read a book because everybody is reading that book, or watch a movie because everyone else has watched it..."

Okay, but the boy is an elementary school student, do you really need to write such a story?
